Co-operative learning is becoming increasingly popular and gaining importance in modern education. It is more effective than traditional forms of learning. In this paper, we report the use of ‘Structured’ collaborative learning, in a course “Engineering Chemistry”. The objective of this paper is to investigate the effectiveness of collaborative learning on improving undergraduate engineering students’ learning in the subject of Engineering Chemistry. The students were actively involved and showed more enthusiasm and participation. A survey conducted at the end of the course shows that students were satisfied with the pedagogical approach and the CO is attained.
